Final "Tulloch" Clarification: Enhanced Wetlands Protections

The Environmental Protection Agency (EPA) and the U. S. Army Corps of Engineers have
promulgated a final regulation to strengthen wetlands protection which went into effect on
April 17, 2001.  The new rule will stem the loss of the Nation's wetlands by clarifying the
types of activities that are likely to result in a discharge of dredged material regulated
under the Clean Water Act.  The agencies estimate that since 1998 at least 20,000 wetland
acres have been targeted for ditching, draining, and destruction and 150 miles of streams
channelized because of a regulatory loophole. While today's action is an important step to protect
the Nation's wetlands, there is no regulatory action that can fully close the loophole in the Clean
Water Act that has led to this type of wetlands destruction.

Background

Wetlands provide a number of economically and environmentally important functions such
as flood control, water quality protection, groundwater  recharge, spawning areas for
commercially important fish, and wildlife habitat.  The Clean Water Act requires a permit
before dredged or fill material may be discharged into wetlands. This permit program
ensures that the environmental impacts of proposed discharges are minimized, and that
unavoidable impacts are offset through compensatory mitigation efforts such as wetlands
restoration.  In fiscal year 1999, approximately 21,500 acres of permitted wetland losses
took place, but these were offset by approximately 46,000 acres of compensatory
mitigation.

Each year, valuable aquatic resources are lost due to mechanized land clearing, ditching and
drainage,  and in-stream mining or channelization activities in wetlands  or other waters of
the United States. In 1993, EPA and the U.S. Army Corps of Engineers issued a final
regulation in 1993 (commonly referred to as the "Tulloch rule") to revise the definition of
"discharge of dredged material" to better protect wetlands from these practices. A 1998
court decision, however, found that EPA and the Corps of Engineers lacked authority
under the Clean Water Act to regulate such activities if conducted so as to result in only
"incidental fallback" (excavated material that falls back to substantially the same place as the initial
removal). In May 1999, EPA and the Corps of Engineers issued a final rule modifying the
definition of "discharge of dredged material" in order to respond to the Court's finding and
to ensure  compliance with the Court decision.  In August 2000, EPA and the Corps of
Engineers proposed further revisions that were finalized and went into effect on April 17,
2001.

Since the  1998 court decision, there has been confusion as to what activities are likely to
result in discharges regulated under the Clean Water Act.  Since the Court decision,

-------
upwards of 20,000 wetland acres have been targeted for ditching, draining, and destruction
and approximately 150 miles of streams channelized without environmental review under
the Clean Water Act, and without compensatory mitigation.  The final rule seeks to stem
such losses by clarifying the scope of activities that typically produce discharges subject to
environmental review under the Act.

Final Revisions

The final rule (published at 66 Fed. Reg. 4549) by EPA and the Corps of Engineers
enhances protection of the Nation's aquatic resources, including wetlands, by clarifying
those types of activities that are likely to result in a discharge of dredged material subject to
Clean Water Act Section 404. The final rule modifies the definition of "discharge of       dredged
material" by clarifying what types of activities EPA and the Corps of Engineers        believe
typically result in regulable discharges, based on the nature of the equipment and        agency
experience.  The rule indicates that the Corps and EPA regard the use of mechanized earth moving
equipment to conduct landclearing, ditching, channelization,  in-stream mining, or other
earth-moving activity in waters of the U.S. as resulting in a discharge of dredged material, unless
project-specific evidence shows that the activity results in only "incidental fallback."  The rule also
provides a definition of what constitutes non-regulable incidental fallback that is consistent with the
Court decision.

Additional Protections

Tens of thousands of wetlands acres and hundreds of miles of streams will receive
improved protection as a result of this final rule.  By clarifying what types of activities are
likely to result in regulable discharges, the rule will also help achieve greater consistency and
environmental protection in  implementing the section 404 program's wetlands protections.

State Partners in Wetlands Protection

A number of states have wetlands protection programs, and some of these  do specifically
regulate ditching and drainage activities.  Such state law "backstops" can help stem ditching
and drainage of wetlands within these particular states. However, we believe that without federal
protection, it is difficult to adequately protect common resources such as interstate lakes and
streams that also lie in states that may not have such aquatic resource protection programs in place.

Cost

We do not anticipate that this final rule will result in significant costs for either large and small
entities.  The rule does not alter or enlarge program jurisdiction, but identifies what types of
activities the agencies believe are likely to result in a regulable discharge.  Therefore, it does not
affect a discharger's obligation to obtain a section 404 permit for any discharge  into waters of the
U.S.  This final rule identifies what types of activities are likely to give  rise to an obligation to
obtain such a permit under the definition of "discharge of dredged material" contained in the
agencies' existing regulations.
